CLIP FOR CORNER BEADS OR STRIPS.

Specification of Letters Patent.

Application filed July 13, 1908.

Patented Apr. 26, 1910.

Serial No. 443,296.

citizen of the United States, residing at I/Varren, in the county of Warren and State of Pennsylvania, have invented new and useful Improvements in Clips for Corner Beads or Strips, of which the following is a specification.

My present invention relates to improvements in corner beads or strips of the character adapted to be applied to a corner or other exposed edge of a wall or similar structure for the purpose of protecting the plastering or other wall covering, and it has for its object primarily to provide a simple and improved clip for supporting or securing the bead or strip in position, the clip being so constructed that it may be formed of a single piece of material which is capable of being quickly and easily applied to the bead or strip byinexperienced persons, and when fastened, the clip obtaining a secure hold upon the bead or strip, thereby supporting the same rigidly and firmly in position, the clip being capable of.

resisting forces tending to deflect the bead or strip, which deflection if permitted to occur, would loosen or crack the plastering or other wall covering.

Another object of the invention is to provide an improved clip of this character which is so constructed as to automatically obtain a firm grip upon the bead or strip when the arms of the clip are adjusted to the angle of the corner, the present invention enabling a firm gripping action to be obtained by the clip without requiring the use of tools or other implements, and when the clip is used in connection with a corner bead having a relatively wide base flange, a rigid and firm support is secured which is capable of readily resisting any blows or other strains which may be brought to bear upon the protective bead or strip.

A further object of the invention is to provide an improved corner bead of solid rolled construction and of substantially T- form, this bead being adapted to receive the clip and having a supporting or base flange which is gripped by the clip, the bead by reason of its form possessing the maximum rigidity, and the clip cooperating therewith to provide a firm and solid support when the bead is in position.

To these and other ends, the invention consists in certain improvements, and combinations and arrangements of parts, all as will be hereinafter more fully described, the novel features being pointed out particu larly in the claims at the end of the specification.

In the accompanying drawing: Figure 1 is a perspective view of a supporting clip constructed in accordance with my present invention; Fig. 2 is a perspective view showing a clip of the construction shown in Fig. l

1 applied to a corner bead, preparatory to the application of the bead to the wall; Fig. 3 is a detail view showing the manner of snapping the clip in position upon the corner bead or strip; and Fig. 4: is a sectional view of the clip and bead secured to the corner, the dotted lines showing the surface of the plaster adjacent to the bead.

Similar parts are designated by the same reference characters in the several views.

Supporting clips constructed in accordance with my present invention are capable of being used in connection with corner beads or strips of various forms, the clip being shown in the present instance in connection with a corner head of approximately T-form or a form approaching that of the ordinary railroad rail. This bead in the present instance is provided with the usual ball or head 1 and a base or supporting flange 2, the usual web 3 connect-ing the head and flange, and the base flange projecting laterally at opposite sides of the web. The dimensions of the bead may be varied according to the desired thickness of the plaster at the corner or exposed edge of the wall to which the same is to be applied, or the proportions may be varied in order that the best results may be obtained in each particular case. In order to lessen the weight of the bead, to provide plaster-keying means thereon, and to enable the bead to accommodate the supporting clips, a series of longitudinally spaced slots or apertures 4 are formed in the web portion of the bead, these apertures being preferably of such a size as to ber employed being determined according to the length of the bead or strip or the desired rigidity, and by elongating the apertures (t in a direction longitudinally of the bead, it is possible to place the supporting clips at practically any desired point upon the bead or strip.

In applying supporting clips to the bead or protecting strip, one end of each clip is passed through an appropriate aperture 4: formed in the web of the bead, and each of these supporting clips comprises in the pres ent instance a single length of sheet metal, preferably strap iron, of an appropriate gage and width to afford the requisite stiffness. This strip of metal has its intermediate portion formed by means of dies or other suitable means into a central channel (5 which is adapted to straddle and rest upon the longitudinal rib 5 formed by that portion of the web of the bead adjacent to the aperture 4, and those portions of the strip at opposite sides of the central channel 6 are formed into a pair of oppositely arranged channels 7 which are spaced equidistantly at opposite sides of the central channel 6 and are so spaced apart as to receive between them and engage the lateral edges of the base flange 2 of the bead when the clip is in fastened relation thereto. Immediately beyond the lateral channel 7 of the strip, the material of the latter is offset or bent inwardly to form a pair of oppositely arranged ledges 8 and beyond these ledges, the opposite ends of the strip are extended in divergent planes to form a pair of fastening or attaching arms 9 and 10 which may be perforated as shown or otherwise so constructed as to enable them to receive nails or other appropriate devices for securing them to the lathing or any other suitable part of the wall adjacent to the corner to be protected.

In constructing the clip, the attaching arms 9 and 10 thereof are preferably arranged at an angle greater than the angle of the corner to which the clip is to be applied, and while the arms of the clip are in this angular relation, the oppositely arranged ledges 8 are slightly spread apart so that one end of the clip may be passed through the appropriate aperture 4: of the bead, and while one edge of the base flange of the latter rests in one of the lateral channels 7 of the clip, the opposite ledge may be sprung over the opposite edge of the base flange of the bead, thereby causing the opposite edges of the base flange of the bead to be arranged in the respective lateral channels of the clip. In applying the bead and the attached clip to the corner of the wall or other structure, the attaching arms of the clip are bent or otherwise brought together until they rest against the surfaces of the wall adjacent to the corner, and this approaching movement or lessening of the angle between the attaching arms of the clip causes the channeled portions 7 to move together and firmly bind the opposite longi- 'tudinal edges of the base flange of the bead,

while the ledges 8 obtain a firm engagement with the back of the base flange, the binding or gripping action obtained by the channeled portions 7 of the clip preventing longitudinal slipping movement of the bead and also preventing tilting of the same about a longitudinal axis, while the engagement of the ledges 8 beneath the flange of the bead provides a firm abutment or support which will resist blows or other forces tending to force the bead inwardly. By applying nails or other suitable devices to the attaching arms of the clip, the clip may be firmly secured to the wall, and a positive and firm locking engagement is provided between the clip and the bead.

In practice, the use of a clip constructed in accordance with my present invention in connection with a corner bead or strip having a laterally projecting supporting flange has been found very satisfactory, the channeled portions of the clip embracing the longitudinal edges of the supporting flange on the bead, and the ledges engaging beneath or behind said flange to effectually prevent tilting or twisting of the bead or strip after the clip has been secured so that it is practically impossible for the bead to loosen by reason of blows or strains which are brought to bear thereon. The clip is so constructed that it may be quickly applied to the bead or corner strip with the greatest facility and by inexperienced persons, it being only necessary after the application of the clip to bend the attaching arms thereof together or toward one another until they conform to the angle of the corner to which these clips are to be applied, the approaching movement of the attaching arms serving to auto1natically grip and lock the bead or strip to the clip without the necessity of employing tools to effect this locking action, and as the clip is composed preferably of a single strip of metal which extends continuously from one end to the other without having any portion thereof cut or punched, the maximum strength of the clip is insured.

lVhile it is preferable in most cases to employ the clip in connection with a bead or strip of the character shown, it will be understood, however, that this clip can be employed in connection with corner beads or strips of various forms, it being necessary only to provide a supporting flange or its equivalent by means of which the clip may obtain the requisite grip or engagement with the bead. I also contemplate employing a corner bead or strip of solid rolled T-form, or a form approaching approximately the form of an ordinary railroad rail, it being possible to employ a bead of this character either in connection with the clip shown or in connection with clips of diflerent forms, and in each instance, a corner bead or strip of the solid form described will possess the maximum rigidity and beads of this form can be manufactured cheaply.
